    Subject[PATCH 1/4] msm_serial: Use relative resources for iomem
    Date
    Device tree iomem resources are only accessible by index, and not by
    name. The msm_serial devices always have either 1 or 2 iomem
    resources, that are always in the same order. Convert the
    platform_get_resource_byname into just platform_get_resource to
    facilitate device tree conversion.
